Control android screen remotely

Hello guys,

I have been searching for a way to control my Android wall tablet for a couple of situations. One example is that when the alarm is on, I want the tablet not just display the Home Assistant front-page, but the Home Assistant alarm page (with buttons and such). Another example is that I also want something like; when watching TV not the Home Assistant app is displayed at default, but a remote for my TV (another app on the tablet). Or when some rings the doorbell the live stream of my security camera at the front door is displayed at default on the Android tablet.

So my question is: is there any way to control an Android device remotely through an API or anything to change the default display of the current application/webpage or the screen (Brightness/On/Off)?

I already figured out the other part of the automations, so it’s just the part between the Android tablet and Home Assistant I just can’t seem to get working.

I hope you somewhat understand my question and hope you guys have an answer!

Cheers

I haven’t done it myself, but I think you can do that with the Automate notify component. When sending predfined messages, Automate can react on the content and perform actions. There probably is the functionality to open an URL, which will in turn open the browser with that.

An alternative would be to use WallPanel, which can also open URLs when published to some MQTT topic if I remember correctly.
